employed with much success an electric
lamp OF 4,000 caudle-power tor the pro-
lection OF microscopic sections upon a

adhesive matter between the veneer and
the base, passing the two secured parts
under a heated roller to melt the glue and
cause 1t TO enter the pores to the wood,
then hnaliy passing the connected base

ing of the glue.
In the extensive oyster-culture expert
ments OF the United States Government
particular attention is being given to
methods for preserving the young. Wire

this device enabling the operators to pre-
vent the accumulation of mud, the great
foe OF the oyster industry, by frequent
shakings of the baskets. An average
oyster is expected TO yield 10000 900

A boiler furnace in combination with a
CRATE, bridge-wall and smOke-chamb Der is
newly patented invention. There is a
pivotally suspended rear-plate. providing
the only communication to the smoke
chamber from under the plate, which
latter is provided with a rod for swinging
it rearward. An air-channeI through the
base of the furnace communicates with
the gas-duct through an opening directly.
below and opposite TO the dependent plate,
which channel is furnished with a valve
to regulate the admission of air.
For some time past, says Industry. gas
water has been applied directly to asri-
cultural land as a fertilizer, with salts
factory results. An average strength of
about degrees Tw. is employed, and at
this strength a gallon of the water is
equal to about l pound of sulphate of
ammonia. The former will cost about 2s.
per 30 gallons. 1t is applied to the land
from barrel by means of pipe drilled
with holes, just In the same way as the
streets OF large towns are watered. The
quantity used is about 100 gallons per
